Probing A Rare Material Spin State
September 14, 2007 — A group of physicists has found experimental evidence of a highly sought-after type of arrangement of atomic magnetic moments, or spins, in a series of materials. Their work, one of the very few ... > full story -
Ability To Write And Store Information On Electronic Devices Improved
September 13, 2007 — Research provides a more thorough understanding of new mechanisms, which makes it possible to switch a magnetic nanoparticle without any magnetic field and may enable computers to more accurately ... > full story -
Physicists Pin Down Spin Of Surface Atoms
September 12, 2007 — Physicists have successfully measured the atomic spin of an isolated atom, one of the necessary steps on the road to quantum computers and spintronics devices. Using a scanning tunneling microscope ... > full story -
New Clues To Mechanism For 'Colossal Resistance' Effects
August 17, 2007 — Experiments shed new light on some materials' ability to dramatically change their electrical resistance in the presence of an external magnetic or electric field. Small changes in resistance ... > full story -
Discovery Of 'Hidden' Quantum Order Improves Prospects For Quantum Super Computers
July 26, 2007 — Scientists have detected a hidden magnetic "quantum order" that extends over chains of 100 atoms in a ceramic without classical magnetism. The findings, published in Science, have implications for ... > full story -
Thousands Of Atoms Swap 'Spins' With Partners In Quantum Square Dance
July 25, 2007 — Physicists have induced thousands of atoms trapped by laser beams to swap "spins" with partners simultaneously. The repeated exchanges, like a quantum version of swinging your partner in a square ... > full story -
Saturn's Old Moon Iapetus Retains Its Youthful Figure
July 19, 2007 — Saturn's distinctive moon Iapetus (eye-APP-eh-tuss) is cryogenically frozen in the equivalent of its teenage years. The moon has retained the youthful figure and bulging waistline it sported more ... > full story -
Wobbly Polarity Is Key To Preventing Magnetic Avalanches On Disk Drives
July 16, 2007 — New research brings models of magnetic avalanches much closer to reality, helping physicists understand both why they happen and why they don't run out of control, wiping disk drives ... > full story -
